Xikuangshan Mine

Xikuangshan mine (simplified Chinese: 锡矿山; traditional Chinese: 錫礦山; pinyin: Xīkuàngshān) in Lengshuijiang, Hunan, China,^[1] contains the world's largest deposit of antimony.^[2] It is unique in that there is a large deposit of stibnite (Sb₂S₃) in a layer of Devonian limestone. There are three mineral beds which are between 2.5 and 8 m thick which are folded in an anticline that plunges to the south-west. The total mineralised area of the mine has a surface extent of 14 km². There are two different units at the mine, the northern one produces mixed oxide and sulfide such as stibiconite (Sb₃O₆(OH)) and the southern one produces stibnite. Ore is concentrated and refined on site in a refinery with a capacity of 10,000 tonnes of antimony per year.^[3]
